Penentuan kapasitas minimal paddle ditinjau dari sudut tekno ekonomi

The objective of these experiment is to calculate the minimale capacity of paddle from techno-economical stand point. Technically, the quality of the liming product by paddle were better quality than the leather processed by using drum. Usually paddle machine were made of teac wood or brick wall. Based on economic evaluation, the production price of the paddle that were made of teac wood (1000 dm3 and 1500 dm3scale) were Rp. 334,46 and Rp. 285,45 respectivelly, made of brick wall (1000 dm3 and 1500 dm3scale)were Rp. 317, 83 and Rp. 273,56 and used of drum Rp. 353,56. Therefore the paddle machine made of brick wall in 1500 dm3 scale was the most economic machine.
